Abstract

The utility model discloses a tap wrench which comprises a handle and a screw tap. At least one blind hole is opened at the position of the middle of the handle, and the screw tap is installed in the blind hole. The tap wrench is simple in structure, convenient to manufacture, low in cost, beneficial to tapping processing and free from causing the phenomenon that the screw tap falls off during using.

Description

A kind of tap wrench

Technical field

The utility model relates to a kind of machining tool, particularly a kind of tap wrench.

Background technology

In the Mechanical Product's Machining process, often need to use tap wrench that tapping is carried out in the hole on the parts, existing tap wrench structure as shown in Figure 1, mostly be two shanks that have the slide block 6 clamping screw taps 2 of square opening 5, rotatably compress fixedly screw tap of two slide blocks 6 from both sides with two long screw rods 7 again, add two long screw rods 7 of hand-turning in man-hour, drive screw tap 2 and carry out tapping.This tap wrench is complex structure not only, and in tapping process, owing to need the hand-turning screw rod, screw rod is rotated towards loosening direction, make square opening become large, thereby screw tap is come off, can bring inconvenience to process like this, affect normal tapping.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of tap wrench, to reach screw tap is come off, and is simple in structure, the purpose of low cost of manufacture.

For achieving the above object, the technical solution of the utility model is as follows: a kind of tap wrench, comprise handle and screw tap, and place, described handle centre position offers at least one blind hole, in the described blind hole screw tap is installed.

Preferably, described blind hole is square opening.

Preferably, described blind hole has 3, and pore size is different, and the screw tap that can satisfy the different-diameter size uses.

Preferably, on the described handle anti-slip veins is arranged, can avoid in use occurring skidding.

Pass through technique scheme, the tap wrench that the utility model provides is made of handle and the screw tap that is installed on the handle, screw tap is directly installed in the blind hole at place, handle centre position, do not need any fastener, simple in structure, cost of manufacture is low, and is easy to use, and the phenomenon that in use can effectively avoid screw tap to come off.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art.

Fig. 1 is tap wrench schematic diagram of the prior art;

Fig. 2 is the disclosed tap wrench schematic diagram of the utility model embodiment.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.

The utility model provides a kind of tap wrench, structural representation as shown in Figure 2, and this tap wrench is simple in structure, and is easy to operate, can effectively avoid screw tap to come off.

As shown in Figure 2, described tap wrench comprises handle 1 and screw tap 2, place, handle 1 centre position offers at least one blind hole 3, screw tap 2 is installed, during use in the blind hole 3, directly screw tap 2 is put into blind hole 3, without any need for fixture, hand-turning handle 1, and apply downward power, screw tap 2 can rotate, and carries out tapping.

Blind hole 3 in the present embodiment is square opening, also can be tri-angle-holed or pentagon hole, and is all corresponding with the shape of screw tap 2 shanks, the limit number that need to prove the hole is more, shape is near circle, and screw tap 2 is installed in easier skidding when rotating in the hole, so the limit number of blind hole 3 is too much unsuitable.

Blind hole 3 has 3, and pore size is different, and the screw tap 2 that can satisfy the different-diameter size uses, and can certainly have a plurality of.

Anti-slip veins 4 is arranged on the handle 1, can avoid in use occurring skidding.

The tap wrench that the utility model provides is made of handle and the screw tap that is installed on the handle, screw tap is directly installed in the blind hole at place, handle centre position, do not need any fastener, simple in structure, cost of manufacture is low, easy to use, and the phenomenon that in use can effectively avoid screw tap to come off.

In addition, offer a plurality of blind holes on the handle, the screw tap that can satisfy different sizes uses; Anti-slip veins on the handle can be avoided the skidding in the use procedure.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.

Claims (4)

1. a tap wrench is characterized in that, comprises handle and screw tap, and place, described handle centre position offers at least one blind hole, in the described blind hole screw tap is installed.
